Mount Azuma-kofuji, Andesite mountain in Fukushima Prefecture, Japan

Mount Azuma-kofuji is a volcanic mountain in Fukushima Prefecture made of andesite rock with a notable crater visible at its summit. The mountain sits within the larger Mount Azuma volcanic range and can be reached via the Bandai Azuma Skyline road.

Mount Azuma-kofuji is an active stratovolcano of the Azuma volcanic group. Its original name is Suribachiyama, referring to the bowl-shaped crater about 450 metres across. The name Azuma-kofuji came from its resemblance to Mount Fuji when seen from Fukushima city. The Bandai-Azuma Skyline now crosses just below the crater.

Each early spring, melting snow on the mountainside leaves a shape locals call the "seeding rabbit" (雪うさぎ), a sign that the farming season has begun; farmers once started sowing rice nursery beds when it appeared. The mountain's real name is Mount Suribachi, and the name Kofuji comes from its resemblance to Mount Fuji seen from Fukushima city.

The mountain is most accessible from mid-April through mid-November when the Bandai Azuma Skyline road is open for vehicle access. Plan for a moderate hike to the summit, with adequate breaks if you're exploring the crater rim.

The crater rim loop measures about 450 m across and roughly 1.5 km around, taking under an hour back to Jododaira. Descending to the crater floor is prohibited for safety and to protect the vegetation. The mountain's original name is Slippery-bowl Mountain (Suribachiyama), after the bowl-shaped crater.
